Phys.org / Land animals evolved from ocean ancestors—new study unravels the genetics behind the transition
The transition from water to land is a question that still intrigues scientists. Those ancient organisms would have needed to adapt to several new challenges to life out of water. So, how did they do it?
Tech Xplore / Perovskite solar cells achieve over 25% efficiency and long lifespan simultaneously
A KAIST research team has solved the "solar cell dilemma," in which increasing efficiency shortens lifespan, while extending lifespan lowers efficiency. The team developed a technology to precisely control the internal structure ...
Phys.org / Why student samples can mislead: Higher education may shift values toward Western norms
A new study published in Nature Communications finds that worldwide, people with higher levels of education are more culturally similar to those in Canada, the U.S., U.K., and other Anglo, industrialized countries and countries ...
Phys.org / How Neanderthals used a lakeshore in Germany to hunt, butcher and survive
In 1948, a group of amateurs led by a local headmaster in Lehringen, Germany, uncovered the skeleton of a straight-tusked elephant—the largest land mammal known to have roamed Europe—in 125,000-year-old sediments from the ...
Phys.org / Urban blue tits use discarded cigarette butts to protect their nests, study suggests
Discarded litter not only makes our streets and neighborhoods look untidy, but it can also pose a significant risk to wildlife. However, in a surprising development, a study published in the journal Animal Behaviour reports ...
Phys.org / Revealing the origin of polarity inversion in polymer semiconductors
A research team led by Prof. Boseok Kang at Sungkyunkwan University has uncovered the origin of polarity inversion, a long-standing phenomenon in polymer semiconductors that occurs only in certain materials. The team, in ...
Phys.org / Trapped subsurface heat may have triggered Antarctica's sudden sea ice loss
In 2016, Antarctic sea ice, which had previously shown record expansion, shifted rapidly toward unusually low levels. This abrupt shift left scientists scratching their heads, wondering why it had vanished so quickly despite ...
Medical Xpress / A protein may help revive exhausted T cells in cancer immunotherapy
Immunotherapy has been one of the most transformative treatments for cancer patients in recent decades, shifting the emphasis from the broad-spectrum approach of chemotherapy to prompting the immune system's boldest warriors—its ...
Phys.org / The raccoon raiding your garbage bin might just be solving a puzzle—for the fun of it
Ever woken up to find that a crafty raccoon has overturned your garbage bin and spread the discarded contents of your life across the street? Raccoons—sometimes referred to as "trash pandas"—are renowned as excellent innovators ...
Phys.org / Giant craters may reveal if Psyche is a lost planetary core
When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in "The Empire Strikes Back," and we often hear how they are remnants from the birth of the solar system. ...
Tech Xplore / Can AI understand literature? Researchers put it to the test
Even with all the recent advances in the ability of large language models (like ChatGPT) to help us think, research, summarize, and learn complex and technical texts, how do they fare in understanding storytelling and literature? ...
Phys.org / The hidden cost of sperm storage: Ejaculates found to deteriorate across the animal kingdom
Current World Health Organization (WHO) guidelines typically recommend two to seven days of abstinence before taking semen samples or assisted reproduction. However, a new study led by Oxford University researchers suggests ...
